S Claims.

ThisV invention relatesV toa device for cutting.`

pastry shellsfrom a sheet. of dough, yand'has. forY anV object the provision of.. a. device ofA this'kind'.

which is relatively simplev in operation, inexpensive in construction and which will not readily getout of order.

This invention further contemplates. the.v Dro-- vision of a device of this kind comprisingannut'er. cutter for cuttingV apastry shell blank. fromv a sheet of doug-h, andan. inner cutter. journaled.

innericutter throughv an arc ofnot less than.18(l` for radially cutting a central portion from the pastry shell blank.

This invention embodies other novel'features, details of construction andarrangement of parts which are hereinafter set forth in the specifica.- tion and claims, andillustratedin the accompanying drawing wherein:

Fig. 1 is a vertical sectional View showing a pastry shellY cutter. embodying features ofithi's invention.

Fig. 5 is a fragmentary sectional View showinga modified form of this invention whereinthe inner cutter is formed'with a pair of diametrically opposed knife portions.l

Referring now to the -drawing for a better-un"-` derstandingfof this invention,/the pastryshell cutter is shown as comprising a housing 6 having a partition l secured to its lower end and a partition 8 secured to its upper end. The partitions 1 and 8 are formed with bearings 9 and II, respectively, to receive a shaft I2 formed with an annular flange I3 and an annular groove I4. The shaft I2 is held against upward movement by means of the flange portion I3 which engages against the underside of the partition 1. A boss 22: IlW is formedbn the partition 1" andA providedwith an.V apertureto receive a. ball"` I1',. a `compression spring` lland; a..set;scr.ew. 191. The ball.

In the operation' of this device. for. forming a pastry shellfof thetype illustratedin-Fig. 4; the outer cutter? 2l-If` isf. adaptede to be. pressed" down.- wardly to cut-througlrasheet of dough' to'fthus form a pastry shell blank. During this downward movement, the cutting edge 26 and cutting wire 21 of the inner cutter 24 are adapted to cut approximately two-thirds of the distance through the pastry shell blank, after which the linger portions 36-36 are pulled upwardly to rotate the shaft I2 and the cutter 24 carried thereby through an arc of not less than and thus While thisl device has vbeen shown in the formof a manually loperable ,pastry shell cutter, itzis contemplated that this invention could readily be embodied in a machine comprising a plurality of cutters arranged for simultaneous operation in cutting any desired number ofpastry shells from a large sheet of dough. Y

Referring now to Fig. 5, an inner cutter 44 is provided with a pair of diametrically yopposed knife portions 5-46 having a cutting wire 2T se- A cured to the lower edges thereof for cutting the central portion from a pastry shell blank in the manner heretofore described.

While this invention has been shown in but two forms, it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modications Without departing from the spirit and scope of the claimed invention.

I claim as my invention:

l. A pastry shell cutter comprising an outer cutter for cutting a pastry shell blank from a sheet of dough, an inner cutter journaled for rotational movement with respect to said outer cutter and having its cutting edge disposed above the cutting edge of the outer cutter to cut and circumferentially define a portion to be removed from the center of the pastry shell blank, and a wire extending transversely across the bottom of said inner cutter and having its ends connected to diametrically opposed sides of the cutting edge thereof for radially cutting the portion to be removed from the` pastry shell blank upon rotational movement of the inner cutter, mechanical actuating means including a pair Aof gears for rotating said inner cutter relative toA saidy outer cutter through an arc of approximately 1810".'

2. A pastry shell cutter comprising an Youter cutter for cutting a pastry shell blank from a sheet of dough, an inner cutter journaled for rotational movementl with respect to'said outer cutter and having its cutting edge disposed above the cutting edge of the outer cutter to cut and circumferentially denne a portion to be removed from the center of the pastry shell blank, a wire extending transversely across the bottom of said.V inner cutter and having its ends connected to diametrically opposed sides of the cutting edge thereof for radially cutting the portion to be removed from the pastry shell blank upon rotational movement of the inner cutter, gear means for rotating said inner cutter through an arc of approximately 180?, and means for returning said inner cutter to its normal position. i
